Creating Markers
for Allelic
Discrimination
Allelic discrimination plate documents feature the use of ‘markers’ to aid in
organizing and applying detectors based on the loci they target. A marker is a pairing
of two detectors representing chemical assays designed to discriminate between
different alleles of a common locus. The SDS software uses marker information
during data analysis to organize and compare the processed run data.
IMPORTANT! Allelic discrimination plate documents must contain at least one
marker.
1. If the Detector Manager dialog box is open, click to close it.
2. Select Tools > Marker Manager.
3. In the Marker Manager dialog box, click .
4. In the Enter name of new Marker field of the Add Marker dialog box, enter a
name for the new marker, and click .
The new marker appears in the Markers field.
Note: If using the SDS Enterprise Database, you cannot create a marker that
that uses the same combination of marker name and detectors as an existing
marker.
5. Apply detectors to the new marker:
a. In the Markers field, click the new marker to select it.
The software highlights the selected marker.
b. In the Detectors list, select the Use check boxes of the detectors that you
want to assign to the marker.
The software highlights the selected detector.
IMPORTANT! You cannot assign more than two detectors to a marker and the
detectors cannot use the same reporter dye.
6. If evaluating multiple loci, repeat steps 3 through 5 to create additional markers
as needed.
IMPORTANT! You must configure a marker with two detectors before you can
apply it to a plate document.
Note: Click for information on the features of the Marker Manager dialog
box or to delete markers from the Markers list.
7. Apply the marker(s) to the allelic discrimination plate document as explained in
“Copying and Applying Markers” on page 3-15.
